wpagent-mcp

An MCP server that lets Claude — or any MCP-compatible client — actually operate a WordPress site: plugins, content, themes, menus, media, users, WooCommerce, Elementor and WP-CLI.

It talks to your site through the free WpAgent bridge plugin over a REST API where every request is signed with HMAC-SHA256. No site credentials are involved, and no data passes through a third-party service: the connection is client → your WordPress, directly.

Install

Nothing to install ahead of time — the config below fetches it on demand.

1. Install the WpAgent plugin on your WordPress site and activate it.
2. In the WordPress admin, open WpAgent and generate an API key. Choose the permissions you want the assistant to have; a read-only key is a sound way to start.
3. Add the server to your MCP client. For Claude Desktop, in claude_desktop_config.json:

{
  "mcpServers": {
    "wpagent": {
      "command": "npx",
      "args": ["-y", "wpagent-mcp"],
      "env": {
        "WP_SITE_URL": "https://your-site.com",
        "WP_API_KEY_ID": "wpaia_xxxxxxxxxxxx",
        "WP_API_SECRET": "the secret shown once when you generated the key"
      }
    }
  }
}

For Claude Code:

claude mcp add wpagent \
  --env WP_SITE_URL=https://your-site.com \
  --env WP_API_KEY_ID=wpaia_xxxxxxxxxxxx \
  --env WP_API_SECRET=... \
  -- npx -y wpagent-mcp

Environment variables

What it can do

What it will not do

The API has no path to arbitrary PHP, no path to your database, and no path to wp-config.php. WP-CLI execution is disabled unless the site owner adds define('WPAIA_ENABLE_WPCLI', true); on the server, and even then only allowlisted commands run — db, eval, eval-file, shell, server, config and package are always refused.

Safety

• Every request is signed with HMAC-SHA256 and carries a timestamp; requests older than five minutes are rejected.
• Permissions are per key and checked on every route, so a read-only key stays read-only.
• Every call is written to an audit log you can read in the WordPress admin.
• Revoking a key in WordPress takes effect immediately.

Ask the assistant to confirm before destructive actions, and keep a current backup — it can delete content when you tell it to.
